Ray, for your Wii, you are correct in that you have to download Opera for 500 Wii points which you buy from the channel 100points = $1. As far as the keyboard, the Wii will now accept a USB keyboard so any one of the wireless ones with the USB dongle should work. I haven't tried one yet but I have hooked up my wired USB keyboard and it works, but it is still way easier to surf with the PC.

I've only tried to web surf on the Wii without a keyboard, so I don't do it much. I might have to pick up a wireless keyboard and see if that makes the prospect viable, or at least more flavorful.

As to networking the HR20, I used this handy thread at dbstalk. Short version is that there was a few clicks to update the HR20 and then a couple things to do on the PC. I've only done the PC stuff in Windows Media Player, but I think I'm going to try TVersity instead. I'm really just getting started, so I don't honestly know yet if this is going to be worth the effort. Another advantage of putting the HR20 on your network is that you can get (beta) DirecTV On Demand. The downloads are ridiculously slow, but there was some content available that I wouldn't have watched otherwise.

Opera was free until last June then it was a 500 point download. The keyboard only makes it easier to type into the Wii's pop up keyboard instead of pointing and clicking with the Wiimote. I haven't found any other uses for it yet, then again I haven't hooked it up since I found out about the keyboard capability.
